A PRI Flare Gun.
* It would be single-shot and work with the current emergency flares we currently have in-game.
* Firing flares would essentially work like sniping with the ability to fire a flare 2-3 rooms in any cardinal direction.
* If fired into the air, the flare would descend slowly illuminating an entire area based on height. Useful in badlands and maybe space?
* Flares would also now come in a bigger variety of color.
* Flare Guns would have a functional combat application due to them essentially being guns. It would not be a good one.
